T0 cZZ io/mm, it may concern Be it known that l, Lewis W. Ecciais'roiv, a citizen ofthe United States, residing at llheaton, in the county of Dupage'and State of Illinois, have invented new and useful Improvements in Steam-Radiators,of which the following is a specification.

My invention relates to 'certain new -and useful improvements in steam 'radiators and is fully described and explained in the specification and drawings, in which- Figure 1 is an elevation o-f part of a system including a radiator embodying my improvements; Fig. 2 is a section on the line 2 of Fig. 1; Fig. 3 is a section on the line 3 of Fig. 1; Fig. 4 is a section on the line 4 4 of Fig. 3, and Fig. 5 is a section oil/the line 5 5 of Fig. 3.

Referring to the drawings, G are the ordinary heating sections of a steam radiator suppliedby a pipe 7. Between the supply pipe and the` sectionsG is a humidifying c evice. This has a steam loop 8 generally similar to those used in an ordinary steam radiator. The space within the loop 8 is, how

ever, inclosed to form a. chamber 9 to which water is supplied by a pipe 10. The chaman outlet-opening 11 at its upper end, this opening preferably being on the side toward the steam sections of the radiator, so that steam issuing from the humidifying device will ent-er the interstices of the radiator thereby humidifying the hot and otherwise' dry air thereof. s

For the purposeof making the humidifying device automatic in its operation, the

" purpose and it may pipe 10 is connected to a tank 12 in which the waterlevel is maintained Vconsta-nt by means of a float-valve 13 of ordinaryfo-rm. The constant level tank 12 may, and preferably does, supply humidifying devices on all the radiators on a given floor in anobvious manner. f

14 is a valve interposed in the pipe 10, this valve being of the type which is opened and closed by electrical means, and 15 is a hygrometer adapted to open and close the circuit controlling the valve 14. Vhile there are various devices available for this be suggested that for ordinary residence, or oi'lice, use, where the Ibeen made in rather tall receptacles.

shown in the accompanyingbeing so between the sect-ions temperature is maintained constant, or sub-' stantially so, any wet bulb thermometer pro l vided with proper electrical contacts may be used to control the circuit.

I am aware that it has proposed tocause the steam within a' ra iator to vaporize water for humidifying purposes. As arule, however, such eiforts'have l have discovered that the reason why such devices are generally unsuccessful is pose to the chilling effects of the air a`c`on* siderable area of the walls ofthe 'water-containing vessel above the water-level therein. As a result the water may boil briskly at the bottom of one of the receptacles, only to condense in the upper part, so that only a small proportion of the water actually passes out-into the room.

heretofore been that they eX- vaporized This diflilculty has been remedied inthe present'device by carrying the steam-section entirely around the water receptacle and as well making the water-receptacle pointed in cross-section at its frontand backedges, the steam section shaped as to lap around the wateri receptacle as best shown in Fig. 9.. By this means the entire water-receptacle is maintained at such temperature that there is practically no condensation in its upper part and the steam issues rapidly from the outlet 11. I have tried devices in which the steam entirely surrounds not" only at ltop,

and under certain conditions such practice might be desirable. `lowever l vhave found that the water may then boil so violently as to issue in liquid. form from the outlet pipe, and I have therefore arrived at subst-antially the cross-section shown in F 2,`as themost desirable. In this form the steam space sufficiently surrounds the water receptacle to prevent condensation inthe upper part thereof but still there is no such excessive heat as will cause the water to boil botto-m and edges, but as well on both faces,"

violently and throw itself -out in liquid forin.

With a 'device of this character.appliedto each radiator in' a building, itis very easy indeed to vaporize enough water to keepl the humidity at a very comfortable point,

I am aware that considerable variation is I possible in the details of the present c ony struction without departing from the spirit thereof, and I do not therefore intend to i tion-is Ato claimv alll the construction asibroadlyas Yis permitted y by the state of the art.

hat I claim ,as new and desire to secure by -Letters Patent, is zwithin said vaporizing `1.YA steam radiator comprising, in combination, steam sections, one of said sections beingv provided with a tacle being provided adjacent-'its upper end with afvapor outlet adapted to discharge diator.

[2. A steam radiator comprising, in combination,` steam `sections, a vaporizing section in series therewith, 'a water receptacle section and in the plane thereof and wholly surrounded thereby on its bottom, top and both edges to. receive heat therefrom,'the said water receptacl'e being provided adjacent its upper end ,vapor through the interstics of theraf' i with a vapor outlet opening adapted to disi bination, steam sections,

charg'evapor through the interstices of the radiator.

3. A steam radiator comprising, in coma vaporizing Section in seriestherewith and provided in'its interior. with a water receptacle in the plane thereof and surrounded thereby on its top, bottom and both edges, said vaporizing secsectionin series therewith, with a water receptacle in the interior thereof, the said water recepceptacle.

'receptacle to ,heat the same.

4. A'steam radiator comprising, in com` bination, with steam sections, a vaporizing water receptacle in the interior thereof and in the same plane therewith to receive heat there-- from, and means to supply water to said re. 40 Iceptacle.

5 A steam radiator comprising, in com! bination, steam sections, a vaporizing se tion 1n series therewith, a Water receptacle sit Wholly Within said vaporizing section and iii' 45 the plane thereof, to receive heat therefrom, and means controlled by the humidity of the apartment .for supplying water to said re` 6. A steam radiator comprising, in conibination, steam sections, a vaporizing sed tion in series therewith, a lwater receptacld wholly within said vaporizing section and in the plane thereof and surrounded thereby on its top, bottom and ceptacle having an outlet positioned to dis1 charge vapor into the interstices of the steam; sections, for the purpose set forth.

In testimony whereof I have hereunto seti, my hand this 1st 'day of July, 1913.
